Falcon Heavy: SpaceX's amazing launch, but what about environmental impact?

SpaceX has now launched the most powerful spacecraft since the Apollo era – the Falcon Heavy rocket – setting the bar for future space launches. The most important thing about this reusable spacecraft is that it can carry a payload equivalent to sending five double-decker London buses into space – which will be invaluable for future manned space exploration or in sending bigger satellites into orbit.

Falcon Heavy essentially comprises three previously tested rockets strapped together to create one giant spacecraft. The launch drew massive international audiences – but while it was an amazing event to witness, there are some important potential drawbacks that must be considered as we assess the impact of this mission on space exploration.

But let’s start by looking at some of the many positives. Falcon Heavy is capable of taking 68 tonnes of equipment into orbit close to the Earth. The current closest competitor is the Delta IV heavy which has a payload equivalent of 29 tonnes. So Falcon Heavy represents a big step forward in delivering ever larger satellites or manned missions out to explore our solar system. For the purposes of colonising Mars or the moon, this is a welcome and necessary development.
